摘要	Contextual seriation, also called occurrence or sequence seriation, is a relative-dating method that orders discrete archaeological units — typically graves or closed deposits — using only the presence or absence of artifact types within them. Its logic is the lifespan assumption: each type is introduced, used continuously for some span, and then disappears, so the contexts in which a type occurs should form an unbroken stretch of the sequence. By permuting the rows and columns of a presence-absence matrix until every type's occurrences cluster into a single contiguous block, the analyst recovers a one-dimensional ordering interpreted as time. The technique originates with W. M. F. Petrie's sequence dating of Egyptian predynastic graves and remains a standard tool for chronology where only incidence data, not abundances, are available.	Ceramic typology is the systematic classification of pottery into named groups — wares, types, and varieties — on the basis of shared attributes of form, fabric, surface treatment, decoration, and manufacturing technology. Because pottery is durable, ubiquitous, and changed rapidly in style, it is the archaeologist's most powerful tool for ordering sites and layers in time and for linking material to cultural traditions. As Prudence Rice's standard sourcebook sets out, a typology is built by recording consistent attributes, partitioning the assemblage into defined types, and arranging those types in a nested hierarchy that can then be quantified and compared across contexts. The resulting type frequencies become the raw material for relative dating, seriation, and the interpretation of trade, identity, and chronology.
